Testing

1. Go to lib directory.
2. Clone LuaJIT 2.1 from repo to LuaJIT dir: git clone https://luajit.org/git/luajit.git LuaJIT
3. Call ./compile_LuaJIT.sh script to get universal libluajit.a
4. Build luajit_app and experiment
5. You can always compare with ./lib/LuaJIT/src/luajit lua_benchmark.lua for example.
6. You can always apply changes to LuaJIT, recompile it with a compile script, and rebuild your app.

Issues at the time of test app creation

1. Without extra entitlements like Allow Execution of JIT-compiled Code or Allow Unsigned Executable Memory script lua_performance.lua needs much more time to be done in comparison to the luajit standalone binary. (On my M2 processor it is etc 0.15 seconds versus etc 19 seconds.) Rarity I see also the app fails with the reason: EXC_BAD_ACCESS (SIGKILL (Code Signature Invalid))
2. With Allow Unsigned Executable Memory I see usually that the first run of the app needs 0.15 seconds to finish the benchmark and from some later runs, it drops to, etc 19 seconds.
